+/* Mike "tamlin" Nordell 2012-09-14 for ReactOS:
+ * NOTE: Wine uses per-GpGraphics id's ('contid' starting from zero in
+ * every GpGraphics). Windows seems to use process-global id's, or at
+ * least more unique id's.
+ * This have the following implications. It:
+ * 1. fails the current gdiplus test case.
+ * 2. is not what Windows does.
+ *
+ * We therefore "obfuscate" the 'contid' a little to more match Windows'
+ * behaviour. The observable behviour should still remain the same,
+ * except for handing out more "unique" id's.
